I am using Win 7 Ultimate. I have the current version of Virtualbox. I downloaded Ubuntu 12.10 from the Ubuntu website and the install as disc image.

Ubuntu probably goes thru about 75% of the install and then I get an error message saying that there is a hardware issue and cannot continue. The error message also says it cannot read the disc, etc, etc.

I have downloaded 2 different versions of Ubuntu. I had downloaded and re-installed VirtualBox twice. I also tried 12.04 but came into the same issue. I downloaded the "desktop AMD-64" Thank you in advance for your help.


Probably you haven't enabled the Virtualization Technology through your BIOS. I cannot help you with that because every one is different.

Try downloading the 32-bit version of Ubuntu. Hope it helps you.

  • Like Ivar Snel said, you should also check that the VM settings are correct you can do this using the Settings button on the main screen. – Cube Dec 15 '12 at 1:04

Make sure you enable PAE/NX and VT-x or AMD-V BUT... Something strange happened in VMware. Whren I enable VT-x there... VT-x is not supported in ths VM. Continue without VT-x? (Or something like that, I don't concentrate (Forget))


Make sure you check the md5sum for the ISO that you download. This simple check can save you hours of frustration.

It does sound like it might be a 64bit virtualisation problem however. Download the 32bit (i386) release, check the md5sum as mentioned, and try installing that.


Ensure that the virtual disk has enough free space for installation of Ubuntu.

I believe Ubuntu Desktop edition needs at least 5Gb free space.
